Answer:

The value of x that makes the equation true is 3

x=3

Explanation:

From the attached image;

Let us write the mathematical equation of the model.

The long bar means x, while the small squares have a value of 1 each.

2x+5=11

solving the equation we have;

\begin{gathered} 2x+5=11 \\ 2x=11-5 \\ 2x=6 \\ \text{divide both sides by 2;} \\ \frac{2x}{2}=\frac{6}{2} \\ x=3 \end{gathered}

Therefore, the value of x that makes the equation true is 3

x=3
